ANTISLIPPING AND ANTIWEARING MATERIAL.

Specification of Letters Patent.

Patented Nov. 3o, 1915.

Application filed January 3, 1912. Serial No. 669,211.

To all whom t may concern.'

.Be it kno-wn that I, RAYMOND B. PRICE, a citizen of the United States, residing at Mishawaka, in the co-unty of St. Joseph, State of Indiana, have invented new and useful Improvements in Antislipping and' Antiwearing Material, of which the following is a specification.

My invention relates to the lmanufacture of anti-slipping and anti-wearing material,

adapted for various uses hereinafter to beI be used, and then embedding said threads in a body of vulcanized plastic material. in such manner that said threads shall be positioned in the material substantially end on. That is to say, said threads will be disposed in their containing material at substantially a right angle to the outer wearing surfaces yof-said material, so'that no amount of wear will alter the character of the surface.

In an application filed by me January 19, 1912, Serial No. 672,261, I have described a process of water-proofing threads which I will prefer to use in treating the threads used with my present invention, but I do not wish to be understood as limiting myself to said method of Water-proofing, it being sufficient that they be made non-absorbent of moisture.

In the drawing accompanying this specification wherein I have illustrated two methods of preparing my improved material: Figure 1 is a side elevation of an article embodying the first step in my improved process. Fig. 2 is a transverse sectional View of the same. Fig. 3 is a view ysimilar to Fig.

' 2 after a further'step in the process. Fig. 4

' the first step in a modified process. Fig. 6

is a transverse sectional View of the same taken after calendering. Fig. 7 is a perspective of the sections .of sheets shown in Figs. 5 and 6 assembled ready for vulcanization.

In said drawing, referring to Figs. 1 to 4, one method of producing my improved material is illustrated, as follows: Taking as a base a solid core 1 of unvulcanized rubber of any suitable shape in cross section I lay upon two sides of the same diametrically opposite each other threads 2 of waterproofed material and then wi-nd around said core and longitudinal threads another thread 3 of water-proof material, the same being wound with its coils as close together as may be desired, as seen in Fig. 1. The article so formed is then passed between rollers and flattened to substantially the configuration shown in cross section in Fig. 3, thereby producing a fiattened sheet having the longitudinal strands lying along each edge thereof. This article is then cut longitudinally and centrally along the line A-A, and produces two similar sections each having projecting from its cut edge the ends of two rows of the threads. Upon now assembling any desired number of these sections with their cut edges uppermost, the same may be united into a homogeneous mass by any suitable vulcanizing operation, and will present a finished article Wlierein the threads are presented in a continuous plane at the wearing surface end on and extending to the base of the article, where they are anchored by passing around the longitudinal thread or cord in loops. By this construction I produce an article wherein the textile threads will always present the same characteristics to the wearing surface, no matter how great the 'wear thereon may be.

By subjecting the threads employed to the action of a water-proofing medium-prior to their use in forming the article, I obviate modification rwherein the threads 4 to be used, Whether treated or not, are first, disposed on the face vof a sheet of rubber`5 and this product is preferably first calendered to embed the threads therein, is then cut transversely into strips to be assembled with the threads disposed end on with respect to the wearing surface, and is finally vulcanized into a homogeneous body.

In this specification heretofore the term end on is intended to include any disposition of the threads at any angle or angles to the wearing surface which will present the ends of said threads to said surface, and said threads may be disposed at any angle to each other.

It will be found that, by reason of the comparative isolation of the threads, their capillary action is materially reduced.

It will be understood that in any of the above processes I contemplate employing in place of rubber such substances as gutta percha. balata, and the like, which will, of course be treated in the usual manner pertaining` to such materials.

I contemplate by my above processes producing articles adapted for use as the tread of a' solid or pneumatic tire, as a matting, as a packing, as a bath brush, as a belt cover, in connection with boot and shoe soles and heels, and for numerous other purposes.

Having thus described my invention, what I claim as neW and desire to secure by Letters Patent is:

l. An anti-slipping and anti-wearing material embodying therein a vulcanized body portion and a plurality of independent, adjacent, non-contacting and substantially parallel brous threads or cords embedded therein with the ends thereof presented in a continuous plane at the wear surface of said body.

2. An anti-slipping and anti-Wearing material, embodying therein a vulcanized body portion and a plurality of independent, ad jacent, non-contacting and substantially parallel fibrous threads or cords embedded in and looped about one edge of said body portion with the ends thereof presented in a continuous plane at the Wear surface of said body portion.

, 3. An anti-slipping and anti-Wearing material, embodying therein a vulcanized body portion and a plurality of independent, adjacent, non-contacting and substantially parallel fibrous threads or cords embedded in and looped about one edge of said body portion with the ends thereof presented in a continuous plane at the wear surface of said body portion, said cords or threads being severally water-proofed.

4. An anti-slipping and anti-wearing material, embodying therein a vulcanized body portion, a plurality of independent, adjacent, non-contacting and substantially parallel fibrous threads or cords embedded in and looped about one edge of said body portion with the ends thereof presented in a continuous plane at the wear surface of said body portion, and means common to a plurality of said threads or cords, interposed between the looped portions thereof and said body portion, whereby each of said cords is anchored with relation to said body portion.

5. An anti-slipping and anti-wearing material, embodying therein a vulcanized body portion, a plurality of independent, adjacent, non-contacting and substantially par allel fibrous threads or cords embedded in and looped about one edge of said body portion with the ends thereof presented in a continuous plane at the wear surface of said body portion, and a fibrous cord or thread common to a plurality of said threads or cords, interposed between the looped portions thereof and said body portion, whereby each of said cords is anchored with relation to said body portion.

6. An anti-slipping and anti-wearing material, embodying therein a plurality of sections united by vulcanization, each section -comprising a body portion embodying therein a plurality of independent, adjacent, noncontacting and substantially parallel fibrous threads or cords embedded therein with the ends presented in a continuous plane at the wear surface of said body portion.

7. An anti-slipping and anti-Wearing material, embodying a longitudinally disposed body portion, separate threads or cords embedded therein and disposed end on toward the Wearing surface thereof, and separate threadsor cords longitudinally disposed around which the inner portions of said first threads or cords are looped.

In testimony whereof, I have hereunto set my hand in the presence of two subscribing witnesses.
